I have a problem with my Pi5 that I already posted about in other topics here. Now I have a new status and can't isolate the issue more. I hope someone here can explain what the problem is and hopefully come up with a solution. ![😊]()
I bought a Pi 5 a couple of months ago. I wanted to use it as a NAS and media center. Therefore I bought the Pineberry Bottom Card and a 4TB SSD (TeamGroup rated 3.3V; 2.5A). It all works fine EXCEPT when I want to make file transfer from Windows 11 PC to Pi5 via my home ethernet. That works only around 2-5 MB/s. After some updates it's been around 10MB/s lately, but far from network capacity.
I have 1Gbit network and tested it to work without issues.
I tested the SSD internally in the Pi. Expected speed around 400 MB/s (tried all modes... Gen 1 to 3).
I tested speed between my Pi and my Windows 11 laptop with iPerf. Works close to 1Gbit/s.
I tried to use the SSD in an enclosure via USB-3. Slightly faster around 15-20MB/s.
I tried loading an image to the SSD and boot from it. Worked fine but same issue with file transfer via ethernet.
I bought another Pi kit and tested all setups again... all the same results. In either setup I even got an insufficient power warning once in a while.
Then I tried with a smaller 256GB SSD (ADATA Legend 700 rated 3.3V and unknown ampere). Same speed as the 4TB SSD.
Then I tried an older 1TB SSD from Samsung rated 3.3V and 1.5A. Same issue.
Then the other way around... copying from Pi5 to Win11 laptop... BANG! 110 MB/s... or close to 1Gbit data transfer.
Oh... and I also bought the Pimoroni SSD hat... same issue.
So WHY can Pi5 send files at optimal speed, but it cannot receive at optimal speed when data goes to and from a SSD??
I wonder if there is some IRQ-issues on the Pi5? Seems the ethernet and SSD doesn't get along perfectly!
I spent weeks testing and searching info online without luck. It ought to work at optimal speed with data transfer via ethernet EACH way.
Looking forward to a response.
Best regards
